Spiral chute for coal preparation

Spiral chutes for coal selection: 1. Introduction: Fiberglass reinforced plastic spiral chutes summarize the characteristics of gravity separation spiral chutes, spiral chutes, shakers, and centrifuges for mineral processing. After being evaluated by relevant scientific research, design, school, and concentrator units organized by the Ministry of Metallurgical Industry, it is believed that this machine has excellent performance, advanced sorting goals, and has been awarded the Science and Technology Research Achievement Award by the Ministry of Metallurgical Industry. It has been widely used in non-ferrous and black mining metals. This product is suitable for separating fine materials with Granularity of 0.3-0.02mm to obtain iron, ferrotitanium ore, chromite ore, pyrite, zircon ore, Rutile ore, monazite ore, phosphorus, tungsten sand, tin ore, tantalum niobium, tantalum niobium ore and other non-ferrous metal ores, rare mineral metals or non-metallic mineral bodies with gravity differences. 2、 The technical principle is that the mineral mortar is slowly fed onto the rotating groove surface through a feeding groove installed at the head of the spiral groove for sorting. The tail of the spiral groove is equipped with a valve type product selection groove, which divides the selection equipment into three categories according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper enables the multi-directional mineral flow to be differentiated and converged. The transverse surface of the fiberglass chute and the slope change of the curve are particularly suitable for the selection of fine particle materials. Spiral chutes for coal preparation 3. Features 1. Stable separation steps and easy operation 2. Large allowable range of feed density 3. Very high enrichment ratio and high recovery probability 4. Small land occupation and low water consumption 5. Simple structure, no power required 6. Large processing capacity 7. Easy installation and operation 8. Small investment, quick effect, spiral chutes for coal preparation 4. Classification according to the Granularity of ore materials processed, Chutes can be divided into three categories: (1) Coarse grained chutes. The maximum Granularity of the feed is more than 2-3mm, and the maximum can be 100-200mm. (2) The ore chute is used to handle 2-3 millimeter sized ore materials. (3) Slurry chute, with a feeding particle size less than 0.074MM. 5、 The application field of fiberglass chute is used for processing 0.6-0.03MM and vein ore and ore sand, but it is unfavorable for sorting when the mud content is high. Currently, it has been widely used for processing iron ore, tungsten, sand tin, tantalum niobium, coastal and riverside sand mines, placer gold mines, and so on.
